Molecular dynamics simulations of high-energy collisions (initial kinetic energies Eo k = 10-106 eV) of Krn, (n=8-512) clusters with a rigid Pt surface provide a microscopic description of the formation of an intracluster shock wave (temperatures up to 3 × 105 K and cluster internal potential energies up to ∼ 104 eV) on a time scale of 10-500 fs, which is accompanied by novel ultrafast energy acquisition processes. High-energy ((10-5) × 103 eV) high-yield (0.5%-10%) interatomic KrKr pair repulsive excitation is exhibited, being manifested in outer-shell electronic excitations and ionization, multiple ionization and Auger processes.
